Zack Snyder’s massive hit 300 was released in 2006. Though its sequel didn’t start production at that time, it kind of feels like it did. Very early casting announcements and multiple title changes have made it seem like we’ve been hearing about 300: Rise of an Empire for years.

All that can now be put aside, because on March 7 Noam Murro‘s sequel starring Sullivan Stapleton, Eva Green, Callan Mulvey, Hans Matheson, Lena Headey and Rodrigo Santoro is finally hitting the big screen. The film borrows many of the distinct visual techniques Snyder used almost a decade ago, but with updated technology and a broader scope.

You can learn more about that and more in a new behind the scenes video released by Warner Bros. Check it out below.
